A fully programmable logic microprocessor with nonvolatile memory provides a user interface through a liquid crystal alphanumeric display. Available WITH or WITHOUT humidity control capabilities.

Heavy duty double wall construction. Interior and exterior finish of heavy gauge steel painted with scratch resistant baked enamel. Complete cabinet and door are insulated and sealed with 100% UL Class 1 rigid polyurethane foam insulation. The foamed-in-place insulation provides low heat transfer, improved cabinet performance and prohibits moisture from migrating into the cabinet walls.

The modular system includes expansion slots on the control board for the ability to add optional RS485 serial communication interface. Specification sheet.

Conditioning System: Precision control provided by the uniform distribution of air through a ceiling plenum. The plenum delivers conditioned air evenly through out the chamber providing maximum uniformity and efficiency. A heavy duty refrigeration system provides rapid removal of heat caused by door openings or product load. The system accurately delivers cooling based on demand and modulates the system to provide precision control. The system utilizes environmentally safe non-toxic CFC free refrigerant, with air-cooled, hermetically sealed compressor backed by a 5 year warranty.

The system includes an expansion valve system to optimize capacity and efficiency. Heating is provided by an incoloy tube heater.

The complete cabinet is UL and C-UL listed.

Performance Ratings for SCRI-1S24 Temperature ONLY Test Chamber:

Temperature Variation: +/-0.5°C @ 4°C to 70°C.  The published temperature variation is derived from the maximum deviation of the thermocouple located nearest the chamber geometric center during the entire test period.  (i.e. 25.0°C min and 26.0°C max divided by two would be a variation of +/-0.5°C).

Temperature Uniformity: +/-1°C @ 4°C to 70°C..  The published temperature uniformity is derived from the maximum deviation of 9 thermocouples are placed on 3 horizontal planes, each plane having the thermocouples evenly spaced diagonally across the shelf from the left and right inner wall, and the middle sensor placed in the approximate geometric center of the shelf.


Performance HSCRI-1S24 Humidity and Temperature Test Chamber

Humidity Variation: +5% @ 5°C to 60°C and RH within performance graph.  Humidity variation is derived from the maximum deviation of the humidity sensor during the test period.

Performance data is based on 23°C, 50%RH ambient conditions, type T-24 Ga. thermocouples with 1.0oz. Brass slugs attached and no product in the chamber.  Data may vary if; ambient conditions change, product load is added, or other changes cause interference to chamber airflow.

Humidification / Dehumidification:

Relative humidity is induced by a highly efficient centrifugal atomizer with a sealed motor and low maintenance reservoir. Dehumidification is achieved by the use of a separate dehumidification latent coil. Both systems are precisely controlled by the programmable logic microprocessor.

The humidity controller utilizes a dry capacitance type sensor for rapid response to humidity changes with exceptional accuracy. The humidifier requires a water source with low mineral content; i.e., resistance of 0.5 - 1.0 megohm and a pressure of 10 – 100 psi. Reverse osmosis treated water is recommended. The water supply connection requires 1/4” plastic or copper tubing.
